We study the sensitivity of the sound speed to relativistic corrections of the equation of state (EOS)
in the standard solar model by means of a helioseismic forward analysis.
We use the latest GOLF/SOHO data for 
, 1, 2, 3 modes to confirm that
the inclusion of the relativistic corrections to the adiabatic exponent 
computed
from both OPAL and MHD EOS leads to a more reliable theoretical
modelling of the innermost layers of the Sun.
Key words: Sun: interior / Sun: oscillations / equation of state
